which analysis can be made to vary considerably by the use of ditiercnt qualities or grades of hydrocarl oils. and also by vary-* trols the volumeof Ct) absorbed by the oil.

Any analysis of gas showing the presence of smalliquanttttes of (1) simply indicates that an excess of free (0 has been admitted 3 by valve through pipe which has not undergone decomposition in the retort and serves only as a diluent of the finished gas.

l pon emerging from the dccomposer S) the gas'is conducted through the pipe 10 to the washing tank 11. thence through pipe 1'. through check valve 13 to the receiving or storing tank 14.

The decomposing chamber 9 and material therein contained may be heated by any suitable means. but I preferably heat the same by the combustion of the gas generated by the apparatus, said gas being conducted through the pipe 15 to the burner 16 beneath said retort or decomposing chamber 9.

In the operation of myimprovtalprocess I obtain from the coml'iination of two comparatively inexpensive products a fixed compound gas of commercial value. which is under a-natural pressure of substantially 900 pounds, to the square inch. which pressure corresponds to that of the initial mixture,

this pressure lending to the gas additional value for mechanical purposes. This high pressure originally in tank 1 serves to force the contents thereof into the crude oil tank 2. to cause a thorough molecular intermixture of the two tnate1-ialsand then to force this mixture at a suitable velocity. which may be controlled by the several controlling valves. through the decomposing and converting chamber into the storage tank where itas fixed gas is retained at approximately its initial pressure. In addition to the value of this gas for mechanical work this pressure performs the function of reducing the volume of the gas into a very compact form greatly facilitating its. storage. and distribution.

llaving thus described my invention. what 1 claim as new and desire to secure by Letters Patent, is:

1. The method of making a tixcd gas which consists in intcrmixing hydrocarlmn oil and isolated carbon dioXitl under pressure and decomposing the mixture by subjecting the same to a high degree of heat.

The method of making a fixed gas which consists in intermixing hydrotau'lam .oil and isolated carbon dioxid under pres- Q same along the face or through the pores sure. decomposing the mixture by subject v ing the same to a high degree of heat, and

collecting the resultant gas in a receptacle at ubstantially the initial pressure.

h'lhe method of making gas which consists in saturating.bydroarhon oil with isolated carbon dioxid. and subjecting the satumted mixture to appr ximately 1400 degree F. of heat to decompose the whole into a fixed gas.

4. The method of making a gas which consistin mixing isolated (lioXitl and bydroearbrm oil under pressure. subjecting the mixture to a high degree of heat to deeotm pose and convert the same into a fixed gas, and t'oiietting thi gas still under pressure in a suitable receiver.

3. The method of making a fixed gas which consists in mixing h drocarbon oil and i olated carbon dioxid under pressure. decompcsing the mixture by passing the of heated porous material. washing the gas. and then millet-ting the same in a suit-able receiver at substantially the initial pressure.

(3. An apparatus for making gas comprising a rtser oir of carbon dioxid under pressure. a reservoir of lrvdrocarbon oil. means for permitting said carb n dioxid and said oil to mix and for preserving the carbon dioxid in i olated c ndition prior to such mixing. a decomposing retort. means for heating said retort. a receiver. and means for conducting said mixture from its reservoir to said retort and the resultant gas from said retort to said receiver.

7. An apparatus for making gas comprising a reservoir ofcarbon dioxid under pressure. a reseryoir of hydrocarbon oil. means for admitting said gas into the lower portion of said oil reservoir whereby the two are mixed. said means being formed to preserve the carbon dioxid in isolated condition prior to such mixing. a retort containin; refractory material. means whereby the generated fixed gas may be used for heating said retort and its contents. areceiver, and

means whereby the richness of said mixturemay be regulated and conducted under pressure from its reservoir through said retort and the resultant gas from said retort to said receiver.

in testimony whereof I alhx my signature in presence of two witnesses.
